iacinia superiora latiora. Stamina 2 infra fcabum 
-corolla, antheris subsessillis. Ovanum s ape rum, 
stylus 1, stigma simplex. Capsula globosa sulcata 
quadrivalvis, unilocularis, polysperma, semina ob-

Obs. This new genus, which I have dedicated to 
Robin,by a transposition of the letters of his name, 
(there being already a genus Robinia ,) does not 
belong to this order ; but to the family Gratiolina 9 
in the natural order Chasmanthia : it differs from 
Gratiola by the calyx and the capsul, which is 
similar to those of Calceolaria, Pederota , but 
the Nibora has not a ringent corolla, Raf. 
105. Nibora aquatica. Raf. Glaberrima, foliis oppo¬ 
site, sessilibus, ovalis, acutiusculis subserratis ; 
floribus axillaribus, solitaris, pedunculatis, brac- 
teatis. Raf*—Acanthe des Marais. Rob. p. 381. 
Grows in swamps and in waters ; the stems are 
thick, fleshy, a little branched, about a foot high : 
sepals of the calyx linear, corolla white : blossomg 
in March. 
Order iv,*—Jasminea. 
106. Fraxinus discolor. Raf. Foliis plerumque 7 phyl- 
lis, rachis tereti, petiolis sulcatis, foliolis ovatis, 
acuminatis, denticulatis, subtus tomentosis. Raf 
Frene gras. Rob. p. 382. Perhaps one of the 
supposed varieties of F. pubescens or nigra. A 
large tree, over 60 feet ; its wood is brittle and 
difficult to split, the folioles are very large, about
